М.б. другими словами. Кто-нить поправьте меня, пожалуйста.

Is this Ivan's book? and Is this book Ivan's? are (pretty much) identical in their meaning; the difference would be of stress:

Это книга Ивана = This book belongs to Ivan (with stress on whose book it is)
Эта книга Ивана = This particular book belongs to Ivan (with stress on which particular book)
